At Christmas the 20 deserving souls each received 6s 8d, and the 40 at Easter, 13s 4d.
Philip Southcott Esq. Had purchased Woburn Farm, alias Cocks lands, consisting of about 25 acres (100,000 m2), in 1735 from a Mistress
Hornby. He was the first person to develop the idea of a combined ornamented farm and garden.
The property lies on the two sides of a hill, and on a flat at the foot of lieutenant The brow of the hill commands two prospects.
The one over a fertile plain watered by the Thames and broken by Saint Ann’s Hill and Windsor Castle, a large mead below spreading to the banks of the river. The other view is more wooded, and from this the bold arch of Walton Bridge is a conspicuous object equally singular and noble.
When Mr. Southcote died in 1758, without issue, he gave this place to his lady.
She died in 1783 and the trustees made the settlement as directed.
